Answer :

This should be a nice and simple answer to your question.

The formula for working out the volume of a cuboid is
Volume=Length×Width×Height

This can be shortened to
V=l×w×h
Or
V=lwh

So, now you know the formula, on to the question

Work out the volume of a cuboid 6cm by 4cm by 2.5cm

Find the relevant information

6cm 4cm and 2.5cm

Write out the formula

V=l×w×h

Substitute in the values

V=6×4×2.5

Solve the equation

V=60

Volume is always a cubed number so remember to add the cubed sign next to your answer (³)

So your final answer will be
Volume=60³

I hope that this has helped you.
Do the LWH rule.
